Yes, yes, yes, use them! Enjoy them, feel good under them, lie on them, let the kitty cats snooze on them, wash them when they need it, dry them in the positive energies of the sun, be proud that you made them and that good things are happening thanks to them...
I used to be afraid to use the nice things people gave me as presents, or that I bought, until I discovered that nice perfume goes off if you don't use it, the elastic on pretty underthings dies and so the pretty, silky things are unusable... Such a waste of lovely things.
Use them, enjoy them, appreciate them!
